Theknoloji ea Welding ke eng?

Welding ke ts'ebetso e kopanyang ka ho sa feleng likarolo tse peli tse arohaneng ho e le 'ngoe ka ho futhumatsa kapa ho hatella ho theha maqhama a athomo. E arotsoe haholo ka mekhahlelo e meraro: fusion welding, welding khatello le brazing.

Fusion welding e theha manonyeletso ka ho futhumatsa le ho pholisa, ho kenyelletsa welding ea tšepe e sirelelitsoeng, welding ea tšepe ea khase, welding ea arc e kentsoeng ka metsing, welding ea plasma arc, welding ea laser le welding ea electron beam.

Joalo ka ha lebitso le bontša, khatello ea welding e kopanya li-workpieces haholo-holo ka ho sebelisa khatello ea kantle. Mefuta ea eona e tloaelehileng e kenyelletsa li-welding tsa resistance, friction welding, ultrasonic welding le explosive welding.

Brazing ke mokhoa oa ho kopanya o sebelisang litšepe tsa ho tlatsa tse nang le ntlha e qhibilihisang ho feta ea lisebelisoa tsa motheo. Filler e qhibiliha ebe e tlatsa lekhalo le kopantsoeng, le oelang ka mefuta e 'meli e meholo: solder e bonolo le brazing e thata.

EHSSe na le lisebelisoa tse tsoetseng pele tsa tlhahiso le tsebo ea morao-rao ea theknoloji ea ho cheseletsa e kang mechine ea ho tjheseletsa ka tlas'a metsi le CO₂ e sirelelitsoeng ka khase ea CO₂.Li-welds tsa rona li kopana le maemo a Sehlopha sa 1, Kereiti ea boleng bo phahameng ka ho fetisisa bakeng sa li-welds tsa sebopeho sa tšepe, tse fetisitseng tlhahlobo e matla ka ponahalo, mefokolo ea ka hare le tlhahlobo e sa senyeheng.

TS EN ISO 3834, eo ka molao e bitsitsoeng Litlhokahalo tsa Boleng bakeng sa fusion welding ea lisebelisoa tsa tšepe, ke tekanyetso ea machabeng e ikemiselitseng taolo ea boleng ba tjheseletsa. EHSS e fumane setifikeiti saISO 3834-2(Litlhoko tse felletseng tsa boleng), tse tsamaellanang ka botlalo le litlhoko tsa mmaraka oa EU. Re sebelisa mekhoa e phahameng ea ho tjheseletsa ho fana ka mehaho ea tšepe e nang le boleng bo phahameng, polokeho le botšepehi.
